Enlarged Prostate (BPH) Supplements and Remedies

To treat an enlarged prostate, some people use herbs, from flaxseed to stinging nettle to prickly pear cactus. At typical doses, experts say that most plant extracts are probably safe for BPH, or benign prostatic hyperplasia. But do they work?

Some supplements may help. Others -- including the most popular, saw palmetto -- might not. And a few, including zinc, may actually put you at risk for getting BPH.

Supplements Most Likely to Work

Beta-sitosterols may help your urine flow better and leave less in your bladder. They may be worth a try, especially if you have high cholesterol. Beta-sitosterols, a plant version of cholesterol, are also used to lower cholesterol and are in some cholesterol-lowering margarines. Try 60 to 130 milligrams a day.

Pygeum, also known as African plum extract, could cut down on the times you have to get up to urinate at night and can improve urine flow. It may not work as well as standard treatments like alpha-blockers, though. Try 75 to 200 milligrams a day. Experts encourage using only sustainably harvested pygeum.

Supplements That May Help

Two studies showed that rye grass pollen extract may relax the muscles of the tube that urine flows through and help bladder muscles contract. You may have less dribbling after urinating and need to get up less often at night to urinate. In one study, it also appeared to shrink prostate size. If you want to try it, it's probably safe for up to 6 months.

Some older research suggests that Harzol, an extract of African wild potato (South African star grass), may ease urinary symptoms. That's probably because it's high in beta-sitosterols. But it may also lower blood sugar levels. So if you have diabetes, you may want to skip products with this plant. And if you do try it, watch your blood sugar closely.
